94 Waverunner 3 exhaust parts needed and question

[sbklf]

I took the exhaust apart and the salt water has ate up the sealing surfaces where the hoses clamp to (major oxidation). I need most of the parts from the exhaust manifold to and including possibly the silencer. New Yamaha parts will cost as much as the thing is worth.

Are there aftermarket exhast systems that would be cheaper maybe?

Is there a used parts classified here on I boats?

This is a long shot but I have a Kawasaki 1100 3 seater (I think it is a 96) that I will part out and would be willing to trade parts from it.

Thanks, Kevin
